Detailed explanation-1: -The ‘competitive exclusion principle’ (CEP) states that two species with identical niches cannot coexist indefinitely.
Detailed explanation-2: -The principle of competitive exclusion was proposed by G.F. Gause which states that two species competing for the same resources cannot coexist. This law is also known as Gause’s law. One population will drive off the other one.
Detailed explanation-3: -Gause’s principle of competitive exclusion states that two species competing for the same limiting resource cannot coexist in the same niche indefinitely.
Detailed explanation-4: -The competitive exclusion principle says that two species can’t coexist if they occupy exactly the same niche (competing for identical resources). Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.
Detailed explanation-5: -No two species can have the exact same niche, otherwise they would be in direct competition for resources with one another. If this occurs, then one species will outcompete the other. If the losing species then does not adapt, it would lead to its extinction.
